Data 
A novel feature at PsychExperments is that we maintain a cumulative database that consists of all the data submitted for each of the experiments.  You can download any data you want from this archive using your browser. The download utility permits filtering by experiment name, class or project name, and date. 

There are two data formats available. 

  • One is a csv file (comma separated fields)  that is customized for use with PE_DataAnalysis1.xls. Data are in rows, one row per data participant, plus there are four header lines with information used by the analysis program.  Use this file only if you plan to analyze it with PE_DataAnalysis1.xls.  Download Data from Lab Exercises in this format
  • The second is a csv file that is more generic.  When opened using a spreadsheet program, the data will be in database format with rows for each trial of data and columns for each data entry.  This file can be manipulated directly using spreadsheet functions, which is what PE_DataAnalysis2.xls does for you. Although this file is a csv file in format, we assign a .pe extension to make it uniquely recognizable by PE_DataAnalysis2.xls.

 This Excel file contains our original VisualBasic analysis program from 2001.  It produces a descriptive analysis and graph of means for a pre-determined design, typically a one-way or two-way analysis, using the IVs that are considered most interesting.
